Among the contentious food issues to be addressed by public policy this year is obesity, which affects Americans of all ages. It occurs in 12.4 percent of children ages 2 to 5, 17 percent of those ages 6 to 11 and 17.6 percent of those ages 12 to 19. Is curbing obesity primarily the responsibility of the government? There is, indeed a role for government policy-making in health care, but it’s not intrusive, punitive, arbitrary regulation; it’s allowing market forces to stimulate the production of fresh fruits and vegetables so that they become cheaper and more available to greater numbers of consumers.
